Sure, you got your trust back, why are you blowing up the surviving armors you maniac.
Clearly despite everything at the end there still wasn't enough stuff on fire or exploding.

He can always afford to make more armors, if he had the time and resources to make all the other models autonomous and equippable on the fly. still, what a waste of a Hulkbuster...
Killian's "end" wasn't very convincing - when he was first trapped in the armor I figure he'd be sent to space, but nope, so what followed felt underwhelming - maybe the plan is to pull a Loki and bring him back as an antagonist for Avengers 2, if Thanos still isn't the antagonist for that? Between the tech and the functional immortality, he might give Hulk and the gang a run for their money - and more excuses to go to space to properly dispose of him, who knows.
I liked how they handled the Mandarin, reminded me of how they worked in the classic Captain America outfit in the Captain's own movie. Similarly for Iron Patriot, which initially seemed like a nod to the comics, but became relevant further on.

For all I know about the comics version, it's essentilly the same role with different characters.
FYI, the scene after the credits doesn't reference an incoming movie this time, but there's a nice nod to the recent past and, well, to the very beginning of the actual movie.
